Celtic’s Lewis Morgan, Hearts centre half John Souttar - who both step up from the 21s - and Lewis Stevenson of Hibs have all been handed their first Scotland call-ups, while there are also places for Johnny Russell of Sporting Kansas City and Aberdeen captain Graeme Shinnie.

Souttar’s Tynecastle team mate Jon McLaughlin retains his place among the goalkeepers while Shinnie is joined by Pittodrie team-mate Scott McKenna.

Ryan Christie of Celtic and Norwich City’s Kenny McLean, who have been on loan at the Dons, are also named in the 24-man squad.

Dylan McGeouch and John McGinn are the other Hibs representatives in the squad while Stuart Armstrong, Jack Hendry and Morgan, who spent the second half of the season on loan at St Mirren, complete the Celtic contingent.
